Which one below is not used in determining chi-square testing threshold. a. Number of groups b. Total number of vehicles counted c.

One speed corresponds to only one density c. One volume corresponds to only one density d. One density corresponds to only one speed

Answer 1

1) relationship between among q, u and k is

q = k*u

where q = traffic volume

k = traffic density

u = traffic speed

so correct answer is (b).
